A co-op of dairy farmers plan to invest $50 million in the existing plant and a new building, according to reports, with groundbreaking this fall. City officials said the dairy cheese and powdered milk operation is still under study, pending state tax incentives and permits.

In 2007, Delphi shuttered its Coopersville plant that once employed 500; most of those employees transferred to General Motors Corp. plants in Wyoming and Lansing, or Delphi's valve-lifter plant on Burlingame in Wyoming. Most of the fuel injector production went to a sister plant in Rochester, N.Y.
California dairyman Arie deJong is one of the investors, along with his nephew, Coopersville farmer Tim den Dulk, and a business partner, Dr. Michael McCloskey. One sideline of the cheese and milk business is expected to be a methane-power plant, using an abundance of manure from area cattle to ultimately create electricity.
